Engineering Excellence
Dual-Function Versatility for Modern Architecture
Manufactured by Foshan Derka Architectural Doors & Windows Co., Ltd., our thermal break aluminum Tilt and Turn windows combine advanced European hardware technology with precision engineering. Designed for high-end residential villas, luxury apartments, and commercial towers, these dual-action window systems offer unmatched operational flexibility, security, and climate control.
Operated via an ergonomic single handle, the window sash turns inward 180 degrees like a casement door for full ventilation and safe indoor cleaning of exterior glass. Alternatively, it tilts inward 10 to 15 degrees from the top for secure, rain-proof continuous micro-ventilation.

Operation Principles
How Dual-Function Tilt & Turn Windows Work
Single-handle perimeter hardware allows effortless switching between two distinct operational modes.
1 Turn Mode (Inward Swing)
Rotating the handle 90 degrees unlocks the sash side hinges, enabling the window to open inward completely. This full-aperture opening maximizes interior airflow during pleasant weather and makes glass cleaning safe and convenient from inside elevated floors—eliminating external scaffolding or hazardous window cleaning equipment.
2 Tilt Mode (Top Inward Ventilation)
Rotating the handle 180 degrees engages the bottom pivot hinges while releasing top corner stays. The sash tilts inward at a top-hung angle, providing draft-free, gentle background ventilation. The tilted sash naturally sheds rainwater outward and prevents intruders from climbing through, ensuring round-the-clock safety even when occupants are away.
Technical Performance
Engineered for Harsh Climates & Strict Building Codes
Foshan Derka Architectural Doors & Windows Co., Ltd. builds every profile system using high-grade 6063-T5 aluminum extrusions, polyamide thermal insulation strips, and multi-point locking gear.
Thermal Insulation
High-density PA66GF25 polyamide thermal barrier breaks heat bridge conduction, lowering interior cooling and heating energy losses.
Air & Water Tightness
Triple EPDM weather-stripping gaskets compress tightly around the sash perimeter under multi-point locking pressure to eliminate air leaks and water ingress.
Multi-Point Security
Perimeter locking mushroom cams lock firmly into heavy-duty keep plates on all four sides of the frame, deterring forced entry.
Sound Insulation
Insulated double or triple glazing units (IGU) filled with argon gas effectively dampen outdoor noise pollution by up to 42 dB.

Frequently Asked Questions
Buying Guides & Technical Questions
Common queries from architects, developers, and trade buyers importing aluminum tilt and turn windows.
Tilt and Turn windows feature a single-handle dual mechanism. Turning the handle 90 degrees allows the sash to swing fully inward like a casement door for maximum ventilation and effortless indoor cleaning. Turning the handle 180 degrees tilts the top of the sash inward by 10 to 15 degrees, providing secure, rain-proof background ventilation.
Our tilt and turn windows incorporate high-density polyamide (PA66GF25) thermal barriers between outer and inner aluminum profiles. Combined with double or triple Low-E argon-filled insulated glass units (IGU) and multi-layered EPDM gasket seals, they significantly reduce structural thermal conductivity, achieving U-factors compliant with NFRC, Energy Star, and European passive house criteria.
Yes. Due to their perimeter compression multi-point locking hardware, tilt and turn windows achieve exceptional wind-load resistance, airtightness, and water tightness. Additionally, the inward turn opening allows safe maintenance and exterior glass cleaning from inside the building on elevated floors.
Every order is custom built to measure. Our engineering department prepares detailed CAD shop drawings based on your architectural blueprints. We offer custom anodized, powder-coated RAL colors, fluorocarbon (PVDF) finishes, wood-grain transfers, specialized acoustic or hurricane impact glass configurations, and hardware matching.
We supply comprehensive product test documentation and compliance certificates for global import clearance, including ISO 9001 quality system certification, CE marking for Europe, AS2047 structural and water testing for Australia/New Zealand, and NFRC thermal ratings for North America.
